3. Procedure for Setting Office Data for OAI Services
This section explains the outline, using conditions, and office data setting procedure of the main OAI service
functions.
3.1 Switch Control Facility (SCF)
3.1.1 Functional Outline
The SCF is the facility that executes, from the Application Program (AP), such control operations as
connections/disconnections between NEAX2400 IMX-accommodate terminal (Dterm) and another,
between a Dterm and a C.O. Line Outgoing/Incoming Trunk, etc. The SCF has several functions (FN),
and explanations will be given in the following about “Basic Connecting Function (FN = 1) – Make Call
(Automatic Answer)” which is one of the several functions.
Note:The basic connection function is a function which automatically set a terminal into an outgoing connection
status. Responding to a connection request from the AP, both the calling terminal number and the call
destination number can be designated.

3.1.2 Using Conditions
1. Normal and abnormal operating sequences pertaining to the basic connection of the SCF are as
described below.
[Normal Sequence]
(a) Upon receiving SCF start request from the AP, the NEAX2400 IMX judges the status (idle,
busy, makebusy, etc.) of the designated calling terminal and destination terminal.
(b) If the calling terminal and the destination terminal are idle, the NEAX2400 IMX sends out
Return Result to the AP, and places the calling terminal into an outgoing connection status and
the destination terminal into ringing status.
These are the basic functions.
(c) When the destination terminal designated from the AP is a terminal in the NEAX2400 IMX
and automatic answer is designated as the answer type, both the calling and destination
terminals can be placed into speech status immediately from the status cited in (b) (After zip
tone has been sent to both terminals, the terminals are placed into speech status.).
Note that this service function is valid only when the destination terminal is in line selection
wait status and also automatic answer is designated as the answer type. In other words, if the
destination terminal is in a status other than line selection wait status, the call is to be answered
manually. Further, this service function is valid only when the destination terminal is a station
(D
term: Voice) among the SCF Make Call designations. In other words, if the call destination
is a trunk, this service function does not work.

[Abnormal Sequence]
(a) Upon receiving SCF start request from the AP, the NEAX2400 IMX judges the status (idle, busy, 
makebusy, etc.) of the designated calling terminal and destination terminal.
(b) If the calling terminal and the destination terminal are in a status other than idle, the NEAX2400 
IMX sends out Return Error to the AP.
2. Only digital multifunction telephone (D
term Series E) can be designated as a calling terminal.

3.2 Call ID Notification (SMFN for ISDN)
3.2.1 Functional Outline
This Call ID Notification function is an enhancement of both the Call Termination Notification and the
Answer Notification among Call Status Monitor Facility Notification functions of the OAI system, and
provides the User’s Application Processor for External Computer (UAP) with the caller’s information
when call termination is to be notified about an incoming call from the Integrated Services Digital
Network (ISDN) concerned. Likewise, when the called terminal has answered an incoming call, this
function also provides the UAP with the ISDN caller’s information.
3.2.2 Using Conditions
1. Only when a call has terminated from the ISDN and when the call has been answered, SMFN
message is sent out with the caller’s information added. Note, however, that caller’s information
may not be added to the message depending on the restrictive conditions pertaining to the caller
notification of the ISDN.
2. The number of digits for ISDN caller’s information is maximum 33 for the caller’s number and
maximum 20 for call sub-address.
3. The SMFR cannot monitor ISDN terminal, and thus when a call has terminated to an ISDN terminal
and the call has been answered, SMFN message is not sent out.

4. When an incoming call terminates from ISDN network, ISDN caller’s number information
(subscriber’s number and sub-address) is provided from the central office in the following format.
Subscriber number is maximum 33 digits, and the sub-address is maximum 20 digits, and they are
separated by the separator “*” (OBH).

2. This service cannot be used simultaneously with other MW control services (VMM/MCI: Message
Center Interface/Message Waiting from Station, ATTCON and MAT).
3. The conditions for the telephone that controls MW are as follows.
 MW can be serviced only on a telephone equipped with MW lamp function.
 On a single-line telephone and/or D
term, MW lamp display position is fixed.
 On a single-line telephone, MW lamp flashing cannot be controlled (ON/OFF only).
 MW lamp on/off/flashing, and LCD display can be controlled on a D
term. (MW indication is
available only on a Dterm equipped with the indicator.)
D
term can control only lamp flashing (LCD display cannot be controlled).
4. In the case of MW service by SSFR (Confirm-type < Computer→NEAX > Performer facility), the
same kinds of display (MW, VMS) as those of MCI (Message Center Interface) are possible.
5. In the case of deletion of all the station data and all the type data, only the same data as those of
MCI are deleted. MW service information for stations from the OAI Terminal Control Facility
(TCF) are not deleted.
6. In the case of MW service by SSFR, lamp on/flashing/off is immediately indicated at the time of
one station control. In the case of deletion of all the station data and all the type data, a delay time
of maximum 196 seconds generates until the status of the terminal changes actually.
7. The system configuration for implementing this service is as illustrated below.
